Calcium L-lactate

Calcium L-lactate (CAS 28305-25-1), also known as calcium lactate, is a calcium salt of lactic acid used across food, pharmaceutical, and personal care manufacturing. It delivers bioavailable calcium while functioning as a buffering agent, acidulant, and stabilizer in finished formulations. In food production, it extends shelf life in baked goods and fresh-cut produce by controlling pH and inhibiting microbial growth without imparting strong acidic flavor. Pharmaceutical manufacturers use it as a calcium supplement active in tablets and chewables.

Its high solubility supports consistent dosing and good patient palatability in medical applications. In personal care formulations, it acts as a pH buffer and mild astringent in oral care products, including toothpastes and mouthwashes. Food processors also use it as a firming agent in canned vegetables and as a mineral fortifier in dairy alternatives and infant nutrition products. This versatility makes it a staple ingredient for manufacturers seeking functional mineral enrichment.

Calcium L-lactate is supplied as a white crystalline powder or granules, with granulated forms preferred for direct compression in tablet manufacturing. Standard grades include food-grade (FCC), USP, and Ph. Eur., covering both food and pharmaceutical requirements. Anhydrous and pentahydrate forms are available, with the pentahydrate being the most commonly traded specification. These high-purity grades ensure compliance with international safety standards for global distribution and industrial use.
